Re: Closing PHP tag best practice?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



What I know its a best practice to leave the closing tag in a script
with one php opening tag.Mostly this applies in a script that present a
class, I think its not correct to leave closing tags in  template kind
of script where you have several php tags.
